That cap looks like the four section one under the chassis of my Canadian Philco 3118, which is also mounted in a similar fashion, it was a 1935 model I think. I'm not sure when they came out with that style of cap, maybe 1933 or so, but I have a 48-482 with a very similar style of cap underneath, obviously it was a fairly successful design.
